There-is provided in the hoti'oin of the carburetor an. outlet pipe 32' for 'ixhc hot \YEIi'Ql chamber formed by the jacket 21 and a similar pipe 83 for the intake maniioid 17. ihis niiiniifoid vidcd with an outlet 34: for the purpose of saving 'i'uci when allowing the engine to run on compression. i

The float chanibciis provided with the im zil oil iniot 36 and has pivotaliy niountcid therein at 37 a bracket 38 to one end (if ,whioh is secured the float 39 the other endoi silk brackethaving the iisuai check Valve it) for cont-roiling the passage of fuel into ihc float chamber. In order toheat the fuel in said chain er there is proferiibiy extendiii) ii i) or cap 55 al the .usual Venturi tube ing therethrough an electric coil 41 which is only employed when starting the engine in cold weather. The float chamber 35 is provided with a normally closed drain outlet 42. The flow of fuel from the float chamber 35 to the mixing chamber 24'is regulated by a needle valve 43 controlled by a device 44 which will later be described in detail, and the mixing chamber 24 has mounted therein the pipe 45 which communicates with the float chamber and carries or nozzle 46 employed for spraying the-fuel into said mixing chamber. This mixing chamber is further provided with a butterfly valve 47 carried by the shaft 48 which is controlled by the lever 49.

It will be'understood that a certain,

amount of vapor is formed in thefloat chamber 35 by reason of the hot water in the jacket 21 and in order to feed this vapor into the intake manifold and thus provide a regular flow of fuel to the Venturi tube 46 whereby the back pressure on the intake valve 28 Will be prevented, there is preferably provided a curved pipe 50 one end of which is mounted in the cover of the float chamber 35 While the other end extends into the manifold 17 at 51. The feeding of this vapor from the float. chamber into the intake manifold also aids in causing the burning of all of the fuel, thus effecting a saving thereof. The portion of the hot water jacket 21 which is arranged about the float chamber 35 is connected to the jacket 19 by means of a pipe 52.

The hot air chamber formed by the jacket of the exhaust manifold is preferably supplied with air through an intake valve having a number of openings 54, the size of which is controlled by a rotatable ring so having openings 56 adapted to cover and uncover the openings 54whereby air may enter said chamber and cause the circulation of hot air therein.

The top of the jacket 18 is further provided with a water'dripping device generally indicated by the numcral 57. and which will presently be described in detail, having a connection 58 leadingto a suitable source of supply and adapted to control a flow of water into the jacket 18 and onto the manifold 16. The contact of the water with the manifold will generate steam which will aea semi-circular bafile plate or 1n the chamber 59 steam into the connection 23 and -'thence into the carburetcr too much moisture entercumulate in a steam chamber 59 formed by partition (30 which 'is arranged adjacent the point where the connection 23 enters the jacket 18. This bafiie plate 60 will prevent-(he entrance of i from which would otherwise result in ing the combustible mixture, but said steam will be ome dry and the vapor therefrom will pass over the partition and into the connection 23. It will be apparent from the foregoing description that the provision of the several jackets about the different parts will result in a thorough heating of the mixture before entering the engine cylinders and that the mixture in the intake manifold will be made sufficiently moist to properly enrich the same, and also that a complete and slow burning of they fuelwill be accomplished, whereby an increase of power will be attained in the combustion stroke of the engine cylinders.

The lever 49 and the controlling devices 44 and 57 are preferably operated simultaneously through any suitable connections, (not shown) to a point adjacent the drivers seat and said devices 44 and 57 are similarly constructed, as shown in Figs.'8 and 9, each comprising a body portion 61 having a re cess or chamber 62 therein in which is slidably mounted the needle valve 63 for controlling the passage of a liquid through the 'valve seat 64. said valve 63 being normally forced downward by means of a coil spring 65. Extending transversely of the top of the body portion 61 and connected to the upper end of the needle valve is a valve actuating arm 66 having a roller 67 upon one end adapted to be engaged by an adjustable segmental plate 68 to which is secured one of the connections for operating the device. It will be apparent from this construction that as the plate 68 is adjusted about its, pivot by the connection the same will raise. and lower the arm 66 and consequently the needle valve 63 thereby regulating the valve of the liquid through the opening, or valve seat 69.
